Here are some recent stories of interest.

—Flying Magazine: “NASA’s Asteroid, Comet Hunting Telescope Set to Retire at End of Month“

A NASA space telescope designed to “hunt” asteroids and comets that could pose a threat to life on Earth and orbiting spacecraft will soon burn up in orbit. In late 2024 or early 2025, the agency’s Near-Earth Object (NEO) Wide-field Infrared Survey Explorer—or NEOWISE—is expected to come home in pieces following the conclusion of its second mission later this month…However, NASA has a replacement lined up: the Near Earth Object Surveyor (NEO Surveyor), set for a 2027 launch. The infrared space telescope is the first to be designed specifically for hunting large numbers of NEOs in and around Earth orbit. It has a baseline development cost of $1.2 billion to which NASA committed in 2022.

—NPR: “Volunteers Who Lived in a NASA-created Mars Replica for Over a Year Have Emerged“

Four volunteers who spent more than a year living in a 1,700-square-foot space created by NASA to simulate the environment on Mars have emerged. The members of the Crew Health and Performance Exploration Analog mission — or CHAPEA — walked through the door of their habitat at NASA’s Johnson Space Center in Houston on Saturday to a round of applause…Haston and the other three crew members — Anca Selariu, Ross Brockwell and Nathan Jones — entered the 3D-printed Mars replica on June 25, 2023, as part of a NASA experiment to observe how humans would fare living on the Red Planet.

—Reuters: “Russia Plans to Create Core of New Space Station by 2030“

Russia is aiming to create the four-module core of its planned new orbital space station by 2030, its Roscosmos space agency said on Tuesday. The head of Roscosmos, Yuri Borisov, signed off on the timetable with the directors of 19 enterprises involved in creating the new station. The agency confirmed plans to launch an initial scientific and energy module in 2027. It said three more modules would be added by 2030 and a further two between 2031 and 2033.

A Day in Astronomy: The Tunguska Event

It was on this day in 1908 that about 800 square miles of forest in Siberia were decimated in what was later attributed to an meteor exploding 3 to 6 miles above the Tunguska River area. As a result of the aerial explosion, no impact crater was created from what was called the Tunguska Event.

The meteor that hit Russia has been estimated top be 160–200 feet wide. The asteroid that passed by the Earth yesterday, 2024 MK, has been estimated to be 400 and 850 feet wide. We are lucky that we did not need to go through this again more than 100 years later.

The Tunguska Event is the largest impact event in recorded history. It was this event that later inspired what we celebrate today – Asteroid Day.

Happy Asteroid Day!

Space Stories: Astronomical Damage in Ukraine, An Awakened Black Hole, and Understanding Jupiter’s Giant Red Spot

—Science.org: “A Shattered Window to the Radio Sky“

In November 2023, photographer Eric Lusito made a rare visit to the Braude Radio Astronomy Observatory near Kharkiv, Ukraine, once one of the nation’s flagship scientific facilities. Since his visit, the Kharkiv region, which was partly occupied by Russian forces in 2022 but liberated later that year, has again faced a renewed Russian assault. As of this writing, military specialists say that effort has stalled. Here is Lusito’s account of his visit.

—The Guardian: “Astronomers Detect Sudden Awakening of Black Hole 1m Times Mass of Sun“

The mysterious brightening of a galaxy far, far away has been traced to the heart of the star system and the sudden awakening of a giant black hole 1m times more massive than the sun. Decades of observations found nothing remarkable about the distant galaxy in the constellation of Virgo, but that changed at the end of 2019 when astronomers noticed a dramatic surge in its luminosity that persists to this day. Researchers now believe they are witnessing changes that have never been seen before, with the black hole at the galaxy’s core putting on an extreme cosmic light show as vast amounts of material fall into it.

—University of the Basque Country: “Establishing Age and Origin of Jupiter’s Great Red Spot“

As a popular icon among objects in the Solar System, Jupiter’s Great Red Spot (GRS) is probably the best-known atmospheric structure. Its large size (right now its diameter is that of the Earth) and the contrast of its reddish colour against the planet’s pale clouds make it an object that can be easily seen even with small telescopes…Speculation about the origin of the GRS dates back to the first telescopic observations made by the astronomer Giovanni Domenico Cassini, who in 1665 discovered a dark oval at the same latitude as the GRS and named it the ‘Permanent Spot’ (PS), since it was observed by him and other astronomers until 1713. Track of it was subsequently lost for 118 years and it was not until 1831 and later years that S. Schwabe again observed a clear structure, roughly oval in shape and at the same latitude as the GRS; that can be regarded as the first observation of the current GRS, perhaps of a nascent GRS.

Recent Book: The Wrong Stuff

Here is a book released this month that may be worth taking to the beach.

The Wrong Stuff: How the Soviet Space Program Crashed and Burned is a tale about a space program that wowed the world in the 1950s and 1960s until the U.S. stole the show with the first man on the Moon. However, the Soviet space program may have had problems long before the U.S. leapfrogged it. If you are interested in the space race, then this is the book for you.

This is a summary from the book:

In the wake of World War II, with America ascendant and the Soviet Union devastated by the conflict, the Space Race should have been over before it started. But the underdog Soviets scored a series of victories–starting with the 1957 launch of Sputnik and continuing in the years following–that seemed to achieve the impossible. It was proof, it seemed, that the USSR had manpower and collective will that went beyond America’s material advantages. They had asserted themselves as a world power.

But in The Wrong Stuff, John Strausbaugh tells a different story. These achievements were amazing, yes, but they were also PR victories as much as scientific ones. The world saw a Potemkin spaceport; the internal facts were much sloppier, less impressive, more dysfunctional. The Soviet supply chain was a disaster, and many of its machines barely worked. The cosmonauts aboard its iconic launch of the Vostok 1 rocket had to go on a special diet, and take off their space suits, just to fit inside without causing a failure. Soviet scientists, under intense government pressure, had essentially made their rocket out of spit and band aids, and hurried to hide their work as soon as their worldwide demonstration was complete.

As we watch the Russian military struggle in Ukraine, we are reminded that the Russians and others (North Korea?) have been good at putting on a show, but the truth can be very different.

None of this takes away from the bravery of the Soviet cosmonauts who thrived and died in that space program. As always, the rot was in the system, which could only stand for so long.

Maybe Putin should put this on his beach reading list as he continues to rattle his saber. It may do him and the world some good.

Progress 88 Resupply Mission Approaches ISS

Yesterday saw another successful resupply launch towards the International Space Station (ISS). The Russian Progress 88 uncrewed spacecraft attached to a Soyuz rocket left Kazakhstan early Thursday morning. It will dock with the ISS Saturday morning (which you can watch on NASA TV).

These missions have become so routine that you generally see few if any stories about such missions. That is a sign of an efficient system. The residents on the ISS like boring efficiency as long as it gets them the supplies they need.

Stay tuned for a little more drama when the Boeing Starliner heads to the ISS tomorrow.
