Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA and Sierra Space are preparing for the first flight of the company’s Dream Chaser spacecraft to the International Space Station. Dream Chaser and its companion cargo module, called Shooting Star, arrived at NASA’s Neil Armstrong Test Facility in Sandusky, Ohio, for environmental testing, scheduled to start in mid-December, ahead of its first flight, scheduled for the first half of 2024.
Messier 15 is an immense swarm of over 100,000 stars. A 13 billion year old relic of the early formative years of our galaxy it's one of about 170 globular star clusters that still roam the halo of the Milky Way. Centered in this sharp reprocessed Hubble image, M15 lies some 35,000 light-years away toward the constellation Pegasus. Its diameter is about 200 light-years, but more than half its stars are packed into the central 10 light-years or so, making one of the densest concentrations of stars known. Hubble-based measurements of the increasing velocities of M15's central stars are evidence that a massive black hole resides at the center of the dense cluster. M15 is also known to harbour a planetary nebula. Called Pease 1 (aka PN Ps 1), it can be seen in this image as a small blue blob below and just right of center. via NASA https://ift.tt/aQoCO61
History's second known periodic comet is Comet Encke (2P/Encke). As it swings through the inner Solar System, Encke's orbit takes it from an aphelion, its greatest distance from the Sun, inside the orbit of Jupiter to a perihelion just inside the orbit of Mercury. Returning to its perihelion every 3.3 years, Encke has the shortest period of the Solar System's major comets. Comet Encke is also associated with (at least) two annual meteor showers on planet Earth, the North and South Taurids. Both showers are active in late October and early November. Their two separate radiants lie near bright star Aldebaran in the head-strong constellation Taurus. A faint comet, Encke was captured in this telescopic field of view imaged on the morning of August 24. Then, Encke's pretty greenish coma was close on the sky to the young, embedded star cluster and light-years long, tadpole-shaped star-forming clouds in emission nebula IC 410. Now near bright star Spica in Virgo Comet Encke p...
by Jeff Foust WASHINGTON — Bill Nelson is one step closer to being NASA’s next administrator after his former colleagues on the Senate Commerce Committee voted to advance his nomination. The committee, meeting in executive session April 28, favorably reported his nomination on a voice vote and without debate. The nomination was part of a session that included consideration of more than a dozen other unrelated bills and nominations. The committee’s approval was expected after Nelson breezed through a confirmation hearing one week earlier . At that hearing, members praised Nelson for his expertise on space issues. No members of the committee expressed any reservations about Nelson leading the space agency. “We were really excited that Bill Nelson was nominated for head of NASA,” Sen. Amy Klobuchar (D-Minn.), who chaired the executive session, said in her opening remarks. “I think you all know Sen. Nelson and how much we respect him, and how excited he is. You could just feel it as ...
