A dead NASA satellite is returning to Earth after 38 years in space

After nearly four decades in space, NASA’s retried Earth Radiation Budget Satellite (ERBS) is about to fall from the sky. On Friday, the agency said the likelihood of wreckage from ERBS harming anyone on Earth is “very low.” NASA expects most of the 5,400-pound satellite will burn up upon re-entry. Earlier this week, the Defense Department predicted ERBS would re-enter the Earth’s atmosphere on Sunday at approximately 6:40PM ET, give or take 17 hours.

While it may not be a household name, the Earth Radiation Budget Satellite had anything but a dull history. Per Phys.org, the Space Shuttle Challenger carried the satellite to space in 1984, a little more than a year before Challenger’s heartbreaking demise in early 1986. Astronaut Sally Ride, the first American woman to fly to space, released ERBS from Challenger’s cargo hold using the spacecraft’s robotic arm. During that same mission, Ride’s crewmate, Kathryn Sullivan, became the first American woman to perform a space walk. It was also the first mission to see two female astronauts fly to space together. As for ERBS, it went on to collect ozone and atmospheric measurements until 2005. Scientists used that data to study how Earth absorbs and radiates solar energy. ERBS’s contribution to science is even more impressive when you consider NASA initially expected it would only stay functional for two years.

First-ever UK space flight set for January 9th

In a few days, the first orbital space flight taking off from UK soil might be launching from Spaceport Cornwell. Virgin Orbit has announced that the initial window for its historic “Start Me Up” mission will open on January 9th, Monday, at 22:16 UTC (5:15PM Eastern Time). If the launch needs to be pushed back due to technical issues or inclement weather conditions, the company has back-up dates lined up throughout the month. 

The Civil Aviation Authority (CAA) approved the licenses Virgin Orbit needs to perform launch activities in the UK back in December, following its approval of Spaceport Cornwall’s first launch license. Virgin Orbit is working with the United Kingdom Space Agency (UKSA), Cornwall Council and the Royal Air Force for this mission. 

Seeing as Start Me Up is the “first” in several ways — it’s also the first international launch for Virgin Orbit, as well as the first commercial launch from western Europe — the private space corp said it will “maintain a conservative posture with regard to system health, weather, and all other elements of scheduling.” That ups the probability of a delay, unless everything falls into place for Virgin Orbit on Monday. Even so, the LauncherOne orbital launch vehicle that will be used for this mission is now attached to Cosmic Girl, the Boeing 747 aircraft that will serve as its first stage launch platform. The company had to transport LauncherOne, which was manufactured in Long Beach, California, to the UK to make the journey possible.

In addition to making history, the mission will ferry satellites from seven customers, both commercial and government, to orbit. Its payload include CIRCE (Coordinated Ionospheric Reconstruction CubeSat Experiment), which is a joint project between the UK Defense Science and Technology Laboratory and the US Naval Research Laboratory, and two CubeSats for the UK Ministry of Defense’s Prometheus-2 initiative.

Walter Cunningham, last surviving Apollo 7 astronaut, dies at 90

Walter Cunningham, an astronaut who was the last surviving member of the 1968 Apollo 7 mission, died on Tuesday at 90. The Iowa-born Cunningham served in the US Navy and Marine Corps before joining NASA in 1963 and eventually taking part in the Apollo program’s first crewed (and first televised) flight.

NASA confirmed Cunningham’s death and added that he was “instrumental to our Moon landing’s program success.” According to the Houston Chronicle, Cunningham died in a local hospital of complications from a fall.

Apollo 7 was NASA’s first spaceflight after the 1967 Apollo 1 tragedy, where a fire killed three astronauts during a rehearsal test. This led to a longer-than-usual training period, as NASA shelved human-crewed spaceflight for 21 months following Apollo 1. The crew spent many long hours studying the spacecraft’s design and construction of the Apollo command and service modules (CSM) to help avoid a repeat tragedy, which could have been perilous for the astronauts and the program. Finally, the crew splashed down on Earth on October 22, 1968, after nearly 11 days in space. Apollo 7 further tested NASA’s equipment and helped pave the way for Apollo 11, where the first humans walked on the moon.

Cunningham retired from NASA in 1971 and tried his hand at public speaking, radio hosting, offshore engineering, commercial real estate and venture capital investing. Unfortunately, he also became an outspoken climate change denier. Speaking to Forbes in 2013, Cunningham went through a laundry list of fossil-fuel industry talking points, framing modern NASA as an organization controlled by the media while claiming climate-change science was closer to demagoguery than fact. (For the record, climate change is real, and we’re running out of time to avoid catastrophe.)

“I definitely believe that we lived in the good old days,” Cunningham said in a 1999 NASA interview. “We lived in the golden age of manned spaceflight. We’ve been in space now for over 40 years. The first 40 years of aviation, we went from just barely flying to jet transport, you know. And now, we haven’t moved that far since we went into space. The days through Apollo will be remembered; there’ll never be another time like that again. Even when we go to Mars, it will be different. And I feel just fortunate that I was a small part of this particular time in spaceflight.”

Watch SpaceX’s first launch of the year take 114 satellites into orbit

SpaceX is gearing up to launch the Transporter-6 mission today, January 3rd, and is hoping that the Falcon 9 rocket taking it to space will begin making its way to low-Earth orbit by 9:56 AM ET. The Transporter-6 mission will take off from Space Launch Complex 40 at Cape Canaveral in Florida using a first stage booster responsible for taking over a dozen other previous missions to orbit, including 10 Starlink launches. It’s the company’s first launch of the year and the latest in SpaceX’s series of dedicated rideshare Transporter missions.

Transporter-6 will take 114 payload to space. As NASA Spaceflight notes, those include tiny picosatellites only a few centimeters in size to microsatellites that weight around 200 pounds for both scientific institutions and commercial entities. One customer is EOS Data Analytics, which will launch the first satellite for its agriculture-focused constellation on this mission. A couple of companies is also launching space tugs, or spacecraft that can transfer cargo from one orbit to another, that will deploy payload for customers of their own at a later date. 

SpaceX will livestream the Transporter-6 launch on YouTube, with coverage starting 10 minutes before liftoff is expected to happen. You can watch the live webcast below:
