Dr. Stephen Hawking died on March 14th, at age 76. The New York Times published a thorough review of his life and accomplishments.

NASA’s acting administrator Robert Lightfoot is retiring.

The startup rocket company Rocket Lab plans to launch their first commercial flight this spring. The rocket will be named It’s Business Time which follows in the naming tradition of their first two test rockets: It’s a Test and Still Testing.

Speaking of small rocket startups, Firefly Aerospace used the popular South by Southwest conference to publicly demonstrate an engine test (video below). The engine would power the upper stage of their planned Firefly Alpha rocket.

If you like rocket engine tests, then watch this new video of Blue Origin’s BE-4 engine, posted by Jeff Bezos last week.

The US federal government passed a new funding bill for the remainder of Fiscal Year 2018 last week. The large omnibus bill includes $20.7 for NASA. If you’d like a comparison of NASA’s budget over the years, check out this Wikipdia page.

In Orbit

Over the past two weeks there have been only two orbital rocket launches. The first was a Chinese Long March 2D rocket carrying an Earth-observing satellite. The second was a Soyuz rocket launched from Kazakhstan carrying 3 crew members on their way to the International Space Station.

Oleg Artemyev, Drew Feustel, and Ricky Arnold docked to the ISS successfully this past Friday, two days after launch. They join Anton Shkaplerov, Norishige Kanai, and Scott Tingle for the ongoing Expedition 55 mission.

Swarm Technologies launched four very small satellites in January without license from the FCC. In fact, the FCC had specifically asked them not to launch because they were too small to track. Now Swarm may not be able to receive future licenses.

Around the Solar System

Mission managers on the New Horizons project have chosen the name Ultima Thule for the small Kuiper Belt object which will be visited by the probe next year. The name would not become official until the International Astronomical Union (IAU) can weigh in.

Recent observations from the Dawn spacecraft reveal that the surface of the asteroid Ceres is dynamic, with changing amounts of visible ice and other materials.

The Kepler space telescope, launched in 2009, will likely run out of fuel this year.

The Center for the Advancement of Science In Space (CASIS)  – the organization that manages the ISS as a national laboratory – will be looking for a new executive director after Gregory Johnson steps down.

The White House released their proposed federal budget for 2019, including details for NASA. Here’s a summary from Parabolic Arc of what the budget would include for the space agency. The Planetary Society also has a great summary up on their blog and also covered it in a recent podcast.

Kennedy Space Center’s visitor center has opened a new interactive “Astronaut Training Experience“.

In Orbit

After the launch of a Progress resupply craft to the ISS was scrubbed last Sunday, it was launch successful on Tuesday and docked to the ISS two days later.

Other than the Progress, launched on a Soyuz rocket from Baikonaur, the only other launch last week was a Chinese Long March 3B rocket carrying two global navigation satellites.

ESA celebrated the 10th anniversary of the Columbus modules launch to the ISS.

Two astronauts, Mark Vande Hei of NASA and Norishige Kanai of JAXA, completed a spacewalk on Friday to fix the SSRMS, as well as some other maintenance tasks.

Around the Solar System

The Opportunity rover has now spent more than 5,000 martian days (or “sols”) on Mars. To commemorate the occasion, the JPL rover team commanded Opportunity to take a “self-portrait” mosaic using the cameras on the end of its robotic arm. This is the first time this has been done with Opportunity.

New Horizons has broken the record held by Voyager’s famous Pale Blue Dot image for farthest images taken from Earth. The probe is on its way to an encounter with 2014 MU69 next January. While it is cruising through the Kuiper Belt, it took advantage of its “near” pass to two other objects and took some low resolution images of 2012 HZ84 and 2021 HE85.
