The Launch of PREFIRE to Monitor the Poles

Posted on by onespaceman2000

NASA has more eyes in the skies after the launch on Saturday of its Polar Radiant Energy in the Far-InfraRed Experiment (PREFIRE) mission. One of Rocket Lab’s Electron rocket place the satellites into orbit from the launch facility in New Zealand.

The pair of CubeSats will spend 10 months monitoring the two poles of the Earth and help NASA to better better predict changes to the climate based on changes in the Earth’s ice, seas, and weather.

Tristan L’Ecuyer, PREFIRE’s principal investigator at thebUniversity of Wisconsin in Madison stated:

Our planet is changing quickly, and in places like the Arctic, in ways that people have never experienced before…NASA’s PREFIRE will give us new measurements of the far-infrared wavelengths being emitted from Earth’s poles, which we can use to improve climate and weather models and help people around the world deal with the consequences of climate change.

The name of the mission, PREFIRE, is a little scary given the fires throughout the world said to be associated with climate change. Sadly, we are far from pre-fire and more like mid-fire. We can only hope that better information from the satellites can help us to steer a safer path.

Space Quote: A Private Mission to Save Hubble?

“Perhaps the opportunity with Polaris won’t be there, but NASA can work with Congress and the Administration to request funds for a Hubble reboost or enhancement mission, using a commercial partner where NASA is in the drivers [sic] seat, and the maturity of the space systems is higher and lower risk.”

-Statement by John Grunsfeld, an astronaut who operated on Hubble multiple times, in an NPR story regarding an offer by businessman Jared Isaacman to privately fund a mission to move the Hubble Space Telescope to a higher orbit and conduct necessary repairs to extend the telescope’s life. His offer has been met with some skepticism due to the difficulty of such a mission.

Space Stories: Spaceplane Planned for ISS, AI Assists Astronomy, and Water Older Than the Sun

Here are some recent stories of interest.

—New Atlas: “World’s First Commercial Spaceplane in Final Stages Before Debut ISS Flight“

The world’s first winged commercial spaceplane has arrived at NASA’s Kennedy Space Center in Florida, its final destination before its first mission to the International Space Station (ISS) later this year. Following rigorous testing at Ohio’s Neil Armstrong Test Facility, the Dream Chaser DC-100 spaceplane named Tenacity got the green light to commence final pre-launch preparations, such as finishing its thermal protection system and payload integration, before it hitches a ride on a United Launch Alliance (ULA) Vulcan rocket to deliver 7,800 pounds (3,540 kg) of food, water and science experiments to the ISS.

—MIT Technology Review: “Astronomers are Enlisting AI to Prepare for a Data Downpour“

In deserts across Australia and South Africa, astronomers are planting forests of metallic detectors that will together scour the cosmos for radio signals. When it boots up in five years or so, the Square Kilometer Array Observatory will look for new information about the universe’s first stars and the different stages of galactic evolution.  But after syncing hundreds of thousands of dishes and antennas, astronomers will quickly face a new challenge: combing through some 300 petabytes of cosmological data a year—enough to fill a million laptops…In preparation for the information deluge, astronomers are turning to AI for assistance, optimizing algorithms to pick out patterns in large and notoriously finicky data sets. Some are now working to establish institutes dedicated to marrying the fields of computer science and astronomy—and grappling with the terms of the new partnership.

—BBC Sky at Night: “Earth’s Water is Even Older Than the Sun, Having Formed Billions of Years Ago, Say Astronomers“

How old is Earth’s water? Could it be older even than the planet itself? A team of astronomers say they’ve found the “missing link” that shows how water is delivered from gaseous star-forming regions in space to planets like Earth. The research suggests that Earth’s water is even older than the Sun. The news comes as a result of studies of a dusty planet-forming disc surrounding a star 1,300 lightyears from Earth

Blue Origin is Open for Tourism Again

It has been some time, but Blue Origin is once again bringing tourists into space. Yesterday’s launch from Texas included five passengers and the pilot.

One of the passengers on the New Shepard rocket was former Air Force Captain Ed Dwight. Mr. Dwight was one of the nation’s first Black astronaut candidate, though he never had the opportunity to fly until yesterday. He was also the oldest person to go into space, beating Star Trek’s William Shatner’s age by a few months. After the flight, Mr. Dwight stated, “I thought I really didn’t need this in my life, but now I need it in my life.”

If you are interested in taking such a flight, just visit this Blue Origin link for more information. The site points out that you only need two days to prepare for a flight:

Our on-site astronaut training program is meticulously designed to teach everything you’ll need to know for a safe spaceflight. Over two days, you’ll learn about New Shepard’s mission profile, safety systems, zero-g protocols, and execute mission simulations.

While I am sure plenty of people are happy that this part of the commercial space industry is operational again, I am looking forward to more commercial success with the resupply of the International Space Station, particularly the upcoming launch of the Boeing Starliner.

Starliner Launch Delayed Again

If you were hoping to a Boeing Starliner launch to the International Space Station (ISS) today, then you will be disappointed (again). The launch is not expected until Friday May 25 at the earliest.

In a press release, Boeing noted:

The additional time allows teams to further assess a small helium leak in the Boeing Starliner spacecraft’s service module traced to a flange on a single reaction control system thruster. Pressure testing performed on May 15 on the spacecraft’s helium system showed the leak in the flange is stable and would not pose a risk at that level during the flight. The testing also indicated the rest of the thruster system is sealed effectively across the entire service module. Boeing teams are working to develop operational procedures to ensure the system retains sufficient performance capability and appropriate redundancy during the flight. As that work proceeds, NASA’s Commercial Crew Program and the International Space Station Program will take the next few days to review the data and procedures to make a final determination before proceeding to flight countdown.

All we can do is hope and wait. I expect astronauts Suni Williams and Butch Wilmore, who are ready to crew the Starliner, are even more impatient.

Update: The proposed May 25 launch date is now dead as well. NASA has yet to provide a new date for what will be a historic launch if it ever gets underway.
