NASA Astronaut to Answer Questions from Students in Pennsylvania
NASA astronaut Chris Williams will connect with students in Pennsylvania to answer prerecorded science, technology, engineering, and mathematics (STEM) questions while aboard the International Space Station.
The Earth-to-space call will begin at 12:20 p.m. EST Thursday, Feb. 5, and will stream live on the agency’s Learn With NASA YouTube channel.
Media interested in covering the event must RSVP by 5 p.m., Wednesday, Feb. 4, to Tamara Krizek at: 917-692-5038 or tamara.krizek@davincisciencecenter.org.
The Da Vinci Science Center will host this event in Allentown, Pennsylvania, for students in kindergarten through grade 12, and members of the community. This unique opportunity aims to deepen understanding of space exploration and inspire young people to pursue a future career in STEM.
For more than 25 years, astronauts have continuously lived and worked aboard the space station, testing technologies, performing science, and developing skills needed to explore farther from Earth. Astronauts communicate with NASA’s Mission Control Center in Houston 24 hours a day through SCaN’s (Space Communications and Navigation) Near Space Network.
Research and technology investigations taking place aboard the space station benefit people on Earth and lay the groundwork for other agency deep space missions. As part of NASA’s Artemis campaign, the agency will send astronauts to the Moon to prepare for future human exploration of Mars, inspiring the world through discovery in a new Golden Age of innovation and exploration.

Hubble And The Fingerprints Of An Ancient Merger
This NASA/ESA Hubble Space Telescope image shows NGC 7722, a lenticular galaxy about 187 million light-years away in the constellation Pegasus. This “lens-shaped” galaxy sits in between more familiar spiral alaxies and elliptical galaxies in the galaxy classification scheme. The dark, dramatic dust lanes are the fingerprints of an ancient galaxy merger.
NASA's Orion Spacecraft at Launch Pad
NASA’s Orion Spacecraft at Launch Pad
NASA’s Orion spacecraft, which will carry the Artemis II crew around the Moon, sits at the launch pad on Jan. 17, 2026, after rollout. It rests atop the SLS (Space Launch System) rocket. Orion can provide living space on missions for four astronauts for up to 21 days without docking to another spacecraft. Advances in technology for deep space travel such as life support, avionics, power systems, and state-of-the-art thermal protection will support the crew during launch, landing, and recovery.

NASA to Discuss Early Results of Artemis II Wet Dress Rehearsal
Editor’s note: This advisory was updated at on Feb. 3, 2026, to reflect a change in the start of the news conference and its participants, as well as removing a placeholder for a crew media gaggle.
Following a fueling test of NASA’s SLS (Space Launch System) rocket at the launch pad for the Artemis II Moon mission, leaders will discuss initial results during a news conference at 1 p.m. EST on Tuesday, Feb. 3.
The agency’s SLS rocket and Orion spacecraft arrived at Launch Pad 39B at NASA’s Kennedy Space Center in Florida on Jan. 17. Since then, engineers have been conducting a variety of tests prior to launch. Underway now is a wet dress rehearsal, which requires filling the rocket with the 700,000 gallons of propellant. Call to stations began Jan. 31, and teams are counting down to a simulated launch window opening at 9 p.m. Monday. If more work is needed, NASA may rollback SLS and Orion into the Vehicle Assembly Building after the wet dress rehearsal.
The agency will stream the news conference live on its YouTube channel. A 24/7 live stream of the rocket remains online, as well as a separate feed for coverage of the wet dress rehearsal. Look for individual streams for these events to watch on YouTube. Learn how to stream NASA content through a variety of online platforms, including social media.
Participants in the news conference include:
- NASA Associate Administrator Amit Kshatriya
- Lori Glaze, acting associate administrator for the Exploration Systems Development Mission Directorate
- Shawn Quinn, program manager, Exploration Ground Systems
- John Honeycutt, chair, Artemis II Mission Management Team
Media previously credentialed for launch may join this event in person. To participate in the news conference virtually, media must RSVP no later than two hours prior to the start of the call to Lauren Low in the Office of Communications at: lauren.e.low@nasa.gov. NASA’s media credentialing policy is online.
As part of a Golden Age of innovation and exploration, Artemis will pave the way for new U.S. crewed missions on the lunar surface in preparation to send the first astronauts to Mars.

Moving satellites to meet a plane for rare reentry data
When satellites eventually fall back down to Earth, they mostly burn up because of the friction caused by the atmosphere. Scientific data about this atmospheric reentry process is urgently needed to design future satellites for a quick, safe and sustainable demise at the end of their mission – reducing risks on the ground and in space.
The European Space Agency (ESA) successfully manoeuvred its remaining two Cluster satellites to ensure they can both be observed from a plane as they reenter the atmosphere on 31 August and 1 September 2026.
