A Northrop Grumman Antares rocket carrying a Cygnus resupply spacecraft is seen at sunrise as the Moon sets on Pad-0A, Sunday, Feb. 9, 2020, at NASA’s Wallops Flight Facility in Virginia. Northrop Grumman’s 13th contracted cargo resupply mission with NASA to the International Space Station will deliver about 7,500 pounds of science and research, crew supplies and vehicle hardware to the orbital laboratory and its crew. The CRS-13 Cygnus spacecraft is named after the first African American astronaut, Major Robert Henry Lawrence Jr., and is scheduled to launch at 5:39pm EST.

NASA astronaut Victor Glover trains on POGO–the Partial Gravity Simulator–at the Building 9N’s Space Vehicle Mockup Training Facility at the Johnson Space Center. POGO simulates the weightlessness that astronauts experience in microgravity, and is one method they use to train for spacewalks. Glover is assisted in this exercise by Bill Lee who has been a POGO operator and technician since 1984 and is retiring after more than 35 years of service to astronaut training. Currently, Glover is assigned to the second crewed flight of SpaceX’s Crew Dragon, a part of the Commercial Crew Program, which is working with the American aerospace industry to develop and operate a new generation of spacecraft and launch systems capable of carrying crews to low-Earth orbit and the International Space…

Retired U.S. Air Force Honorary Brigadier General Charles McGee speaks with NASA astronaut Alvin Drew during a Black History Month program titled “Trailblazers, The Story of a Tuskegee Airman.” McGee, a pilot with the Tuskegee Airmen during World War II, and Drew spoke at NASA Headquarters in Washington on Feb. 5, 2020. McGee was a career officer in the Air Force, also serving during the Korean and Vietnam Wars. Over his 30 years of service he flew 409 combat missions. Of the 355 Tuskegee pilots who flew in combat, McGee is one of only nine surviving. Drew has been a NASA astronaut since 2000, flying aboard space shuttle missions STS-118 in 2007 and STS-133 in 2001, the final flight of the orbiter Discovery. Both missions…

NASA astronaut Christina Koch is seen outside the Soyuz MS-13 spacecraft after she, Roscosmos cosmonaut Alexander Skvortsov, and European Space Agency astronaut Luca Parmitano landed in a remote area near the town of Zhezkazgan, Kazakhstan on Thursday, Feb. 6, 2020. Koch returned to Earth after logging 328 days in space — the longest spaceflight in history by a woman — as a member of Expeditions 59-60-61 on the International Space Station. Skvortsov and Parmitano returned after 201 days in space where they served as Expedition 60-61 crew members onboard the station.

Deborah Johnson is long-time employee of NASA, who has spent her entire government career at the agency. Not all NASA personnel are astronauts and scientists. many like Johnson support the Mission Directorates and are the staff who keep the agency functioning at all levels–from administrative tasks to the “cool stuff” like public outreach. Below Johnson talks about her career and motivations. How long have you worked for NASA HQ? I have worked for NASA Headquarters since September 9, 1978 What made you want to work for NASA? I am a Washingtonian, and as a kid, I would visit the museums on the Mall. I had always been curious about space travel. I would visit the Air and Space Museum frequently to satisfy my curiosity for…

2020 February 2 Zeta Oph: Runaway Star Image Credit: NASA, JPL-Caltech, Spitzer Space Telescope Explanation: Like a ship plowing through cosmic seas, runaway star Zeta Ophiuchi produces the arcing interstellar bow wave or bow shock seen in this stunning infrared portrait. In the false-color view, bluish Zeta Oph, a star about 20 times more massive than the Sun, lies near the center of the frame, moving toward the left at 24 kilometers per second. Its strong stellar wind precedes it, compressing and heating the dusty interstellar material and shaping the curved shock front. What set this star in motion? Zeta Oph was likely once a member of a binary star system, its companion star was more massive and hence shorter lived. When the companion exploded…

Astronomers using data from NASA’s Chandra X-ray Observatory and other telescopes have put together a detailed map of a rare collision between four galaxy clusters. Eventually all four clusters — each with a mass of at least several hundred trillion times that of the Sun — will merge to form one of the most massive objects in the universe. Galaxy clusters are the largest structures in the cosmos that are held together by gravity. Clusters consist of hundreds or even thousands of galaxies embedded in hot gas, and contain an even larger amount of invisible dark matter. Sometimes two galaxy clusters collide, as in the case of the Bullet Cluster, and occasionally more than two will collide at the same time. The new observations show…
