The First Explorer


Sixty years ago, on January 31, 1958, the First Explorer was successfully launched by the Army Ballistic Missile Agency on a Jupiter-C rocket. Inaugurating the era of space exploration for the United States, Explorer I was a thirty pound satellite that carried instruments to measure temperatures, and micrometeorite impacts, along with an experiment designed by James A. Van Allen to measure the density of electrons and ions in space. The measurements made by Van Allen's experiment led to an unexpected and then startling discovery of two earth-encircling belts of high energy electrons and ions trapped in the magnetosphere. Now known as the Van Allen Radiation belts, the regions are located in the inner magnetosphere, beyond low Earth orbit. Explorer I ceased transmitting on February 28, 1958, but remained in orbit until March of 1970. via NASA http://ift.tt/2Gxjab3

This Is What Happens When People Try To Work Together in DC

Keith's note: Yesterday @BillNye tweeted this statement: "Tomorrow night I will attend the State of the Union as a guest of Congressman Jim Bridenstine - nominee for NASA Administrator - who extended me an invitation in my role as CEO of The Planetary Society. The Society is the world's largest and most influential non-governmental nonpartisan space organization, co-founded by Carl Sagan. While the Congressman and I disagree on a great many issues - we share a deep respect for NASA and its achievements and a strong interest in the future of space exploration. My attendance tomorrow should not be interpreted as an endorsement of this administration, or of Congressman Bridenstine's nomination, or seen as an acceptance of the recent attacks on science and the scientific community. The U.S. Space Program has long been a source of American technical achievement, a symbol of our innovative spirit, and a source of national pride. There are extraordinary opportunities for our country, and for all humanity, in the continued exploration of space. Historically, the Space Program has brought Americans together, and during his address, I hope to hear the President's plans to continue exploring the space frontier."

Bill Nye and the State of a Polarized Union, Planetary Society

"Space exploration is one of the few areas of politics that still offers significant opportunities for bipartisan rapprochement. A shared passion for space can lay the groundwork for a relationship between individuals of very different political beliefs. This can help build trust and mutual respect between them, and potentially allow them to engage on more contentious issues that would otherwise be immediately dismissed or ignored. The current lack of mutual trust between the parties has been identified as one of the threats to a functioning democracy, and space provides a rare opportunity to try and reverse that trend."

Is Falcon Heavy An SLS Killer?

Elon Musk is set to launch his Falcon Heavy rocket, a flamethrower of another sort, Washington Post

"It could also play a part in the Trump administration's plans to return to the moon. Over the weekend, Nick Ayers, Vice President Pence's chief of staff, tweeted that the rocket would have "major (positive) ramifications for US space industry if this goes according to plan." SpaceX has said that the Falcon Heavy would cost $90 million a launch, a fraction of what NASA's more powerful Space Launch System would cost. Last year, Bill Gerstenmaier, NASA's associate administrator for human exploration and operations, said the SLS rocket would cost about $1 billion per launch. With such a vast difference in price, some have wondered if the Falcon Heavy obviates the need for SLS. "If the SpaceX model works, it creates direct competition to SLS," said Howard McCurdy, a professor of public affairs at American University."

Venus at Night in Infrared from Akatsuki


Why is Venus so different from Earth? To help find out, Japan launched the robotic Akatsuki spacecraft which entered orbit around Venus late in 2015 after an unplanned five-year adventure around the inner Solar System. Even though Akatsuki was past its original planned lifetime, the spacecraft and instruments were operating so well that much of its original mission was reinstated. Also known as the Venus Climate Orbiter, Akatsuki's instruments investigated unknowns about Earth's sister planet, including whether volcanoes are still active, whether lightning occurs in the dense atmosphere, and why wind speeds greatly exceed the planet's rotation speed. In the featured image taken by Akatsuki's IR2 camera, Venus's night side shows a jagged-edged equatorial band of high dark clouds absorbing infrared light from hotter layers deeper in Venus' atmosphere. The bright orange and black stripe on the upper right is a false digital artifact that covers part of the much brighter day side of Venus. Analyses of Akatsuki images and data has shown that Venus has equatorial jet similar to Earth's jet stream. via NASA http://ift.tt/2DKlFVr

Sen. Nelson's Effort To Undermine NASA

NASA has gone a year without a formal leader--with no end in sight, Ars Technica

"Five months ago, the Trump administration finally put forward a nominee for the post of administrator, Oklahoma Congressman and pilot James Bridenstine. Although he was confirmed along a party-line vote twice during Senate confirmation hearings, he has yet to receive a vote before the full Senate. Increasingly, it is obvious that the White House does not have the votes to confirm Bridenstine in a Senate where Republicans hold only a narrow margin. Sen. Bill Nelson, a Florida Democrat, has led opposition to Bridenstine, saying he is too politically polarizing a figure to lead NASA. Nelson has convinced his fellow Floridian Senator, Republican Marco Rubio, to oppose Bridenstine as well."

Has Space Commercialization Finally Arrived?

What Trump Gets Right About NASA, Space Exploration, Eric Stallmer, CSF

"Today, a new generation of commercial space companies is taking the lead on space exploration and aerospace innovation. ... Other firms are developing commercial spacecraft systems to reach the moon and asteroids, land on the surface of other planets and preparing to deploy commercial habitats in space. Despite this progress, some inside the space community remain nostalgic about the government owning and controlling space assets. Late last year at the American Institute of Aeronautics and Astronautics' Space annual conference, for instance, then-NASA administrator Charlie Bolden told audience members that he "is not a big fan of commercial investment in large launch vehicles. ... The alternative, which lawmakers need to begin insisting on? Firm, fixed price contracts. Under this model, which works best with privately owned space hardware, taxpayers shoulder far less risk - and companies are incentivized to complete projects on time and under budget."

Thinking Of Challenger

Thirty Two Years Of Resonance With Challenger, SpaceRef

"On this day in 1986 I was sitting at my desk as a grad student in the Biology Department at Central Connecticut State University. Everyone knew of my interest in space. I had the radio on. I listened to the launch and then stepped out for a moment. I came back and heard the announcer said that debris could be sighted falling into the water. I was crushed. I had a class to teach in 20 minutes or so. We got word that classes were cancelled for the day so I had to go tell my class that they could leave. The day after Challenger was lost I wrote a letter to President Reagan and sent a cc: to my member of Congress. I asked them to name the new moons of Uranus that Voyager 2 had just discovered during its flyby 5 days earlier after the crew of Challenger. The correspondence chain that followed is shown below. Alas they went with the traditional IAU naming convention."

Creating a guidebook for Earth's hypothetical twin

International meetings: Moon initiatives

Cartwheel of Fortune


By chance, a collision of two galaxies has created a surprisingly recognizable shape on a cosmic scale, The Cartwheel Galaxy. The Cartwheel is part of a group of galaxies about 500 million light years away in the constellation Sculptor. Two smaller galaxies in the group are visible on the right. The Cartwheel Galaxy's rim is an immense ring-like structure 150,000 light years in diameter composed of newly formed, extremely bright, massive stars. When galaxies collide they pass through each other, their individual stars rarely coming into contact. Still, the galaxies' gravitational fields are seriously distorted by the collision. In fact, the ring-like shape is the result of the gravitational disruption caused by a small intruder galaxy passing through a large one, compressing the interstellar gas and dust and causing a a star formation wave to move out from the impact point like a ripple across the surface of a pond. In this case the large galaxy may have originally been a spiral, not unlike our own Milky Way, transformed into the wheel shape by the collision. But ... what happened to the small intruder galaxy? via NASA http://ift.tt/2DB4lGF

Bridenstine Nomination Update

Trump has picked a politician to lead NASA. Is that a good thing?, Science

"Although the Trump administration has proposed stiff cuts to earth science at NASA, the Senate has so far warded them off. [Kelvin Droegemeier, vice president for research at the University of Oklahoma in Norman] does not expect Bridenstine to support slashing the agency's budget, especially given that much of NASA's mission can be framed in terms of collecting data that are as applicable to understanding weather patterns as to understanding climate change. "He won't come in and say we're going to discontinue climate financing and take earth science and trash it," Droegemeier predicts. "He absolutely believes the planet is warming, that [carbon dioxide] is a greenhouse gas, and that it contributes to warming." ...

... "But Bridenstine's political chops could serve the agency well, says Laurie Leshin, the president of Worcester Polytechnic Institute in Massachusetts, and a former high-ranking NASA official who was set to help lead Democratic presidential nominee Hillary Clinton's potential transition. "NASA tends to value people who are geeks like them, in a good way," she says. But NASA often has plenty of technical expertise while lacking political savvy. "Somebody with that background, I think we should give him a chance to be successful."

Ribbons and Pearls of Spiral Galaxy NGC 1398


Why do some spiral galaxies have a ring around the center? Spiral galaxy NGC 1398 not only has a ring of pearly stars, gas and dust around its center, but a bar of stars and gas across its center, and spiral arms that appear like ribbons farther out. The featured image was taken with ESO's Very Large Telescope at the Paranal Observatory in Chile and resolves this grand spiral in impressive detail. NGC 1398 lies about 65 million light years distant, meaning the light we see today left this galaxy when dinosaurs were disappearing from the Earth. The photogenic galaxy is visible with a small telescope toward the constellation of the Furnace (Fornax). The ring near the center is likely an expanding density wave of star formation, caused either by a gravitational encounter with another galaxy, or by the galaxy's own gravitational asymmetries. via NASA http://ift.tt/2G3GXiy

What if you could look out from the center of our Galaxy -- what might you see? Two scientifically-determined possibilities are shown in the featured video, an immersive 360-degree view which allows you to look around in every direction. The pictured computer simulation is based on infrared data from ESO's Very Large Telescope in Chile and X-ray data from NASA's orbiting Chandra X-ray Observatory. As the video starts, you quickly approach Sgr A*, the supermassive black hole in the Galactic center. Then looking out, this 500-year time-lapse simulation shows glowing gas and many points of light orbiting all around you. Many of these points are young Wolf-Rayet stars that have visible hot winds blowing out into surrounding nebulas. Clouds approaching close become elongated, while objects approaching too close fall in. Toward the video's end the simulation repeats, but this time with the dynamic region surrounding Sgr A* expelling hot gas that pushes back against approaching material. via NASA http://ift.tt/2BhIheh

Of course, I'll continue - always -- to be a strong proponent of NASA and STEM activities in general."

Clouds in the LMC


An alluring sight in southern skies, the Large Magellanic Cloud (LMC) is seen in this deep and detailed telescopic mosaic. Recorded with broadband and narrowband filters, the scene spans some 5 degrees or 10 full moons. The narrowband filters are designed to transmit only light emitted by hydrogen, and oxygen atoms. Ionized by energetic starlight, the atoms emit their characteristic light as electrons are recaptured and the atoms transition to a lower energy state. As a result, in this image the LMC seems covered with its own clouds of ionized gas surrounding its massive, young stars. Sculpted by the strong stellar winds and ultraviolet radiation, the glowing clouds, dominated by emission from hydrogen, are known as H II (ionized hydrogen) regions. Itself composed of many overlapping H II regions, the Tarantula Nebula is the large star forming region at the left. The largest satellite of our Milky Way Galaxy, the LMC is about 15,000 light-years across and lies a mere 160,000 light-years away toward the constellation Dorado. via NASA http://ift.tt/2Dm6ENt

Bridenstine Nomination Version 2.0

Senate Commerce, Science, and Transportation Committee Executive Session: Bridenstine Nomination

"The U.S. Senate Committee on Commerce, Science, and Transportation will hold an executive session on Thursday, January 18, 2018 at 11:00 a.m. in Hart 216 to consider the following presidential nominations. ..."

Keith's note: In addition to Bridenstine there here are 7 other nominees to be considered at this executive session. During his confirmation hearing in November 2017, the bulk of the questions went to Bridenstine and not to the other nominees sitting at the table. Bridenstine's nomination passed along party lines. With an even larger group of nominees one might expect that there will be fewer questions directed at Bridenstine this time. One would expect, that is.

A live video of the markup and additional information will be available at http://ift.tt/1dX5KON. The session will be live tweeted at @NASAWatch
