NASA’s Opportunity rover snapped the first-ever image of a comet from the surface of Mars during a once-in-a-lifetime opportunity as Comet Siding Spring (Comet C/2013 A1) made the closest known flyby of either Earth or Mars in recorded history—missing the Red Planet by a mere 87,000 miles (139,500 kilometers).
Opportunity captured the spectacular and history-making view of the “fuzzy” Oort Cloud comet by pointing her camera high up in the pre-dawn Martian sky on Sunday, Oct. 19, said “quite excited” Opportunity science team member Mark Lemmon of Texas A&M University, exclusively to AmericaSpace today (Oct. 20). See rover photo above with our enhanced view revealing more comet detail.

MICHOUD ASSEMBLY FACILITY, NEW ORLEANS, LA — The first pieces of rocket hardware have been loaded onto NASA’s gigantic new weld tool tasked with assembling the core stage fuel tanks for NASA’s mammoth new heavy lift rocket—the Space Launch System (SLS)—that will one day boost “Humans to Mars.”
The road to SLS production and first launch has started, with acceptance testing using parts from the over 34,000 square feet of real metal components already manufactured.

Twenty-one years ago, yesterday, on 18 October 1993, the longest flight ever attempted in shuttle history—the 14-day STS-58 mission, carrying the second Spacelab Life Sciences (SLS-2) research payload—was launched into orbit. Aboard Columbia were astronauts John Blaha, Rick Searfoss, and Bill McArthur, together with physicians Rhea Seddon and Dave Wolf, biochemist Shannon Lucid, and veterinarian Marty Fettman. As described in yesterday’s AmericaSpace history article, SLS-2 attracted a measure of controversy, in that it represented the first human space mission to feature the euthanasia and dissection of animals as part of a medical investigation in the microgravity environment.

The Solar System is full of surprises. Mercury, the planet closest to the Sun, is a baking hot world, as would be expected. It is one of the last places where you would think anything would or could be frozen, but things aren’t always as they seem. There has been tantalizing evidence already for water ice deposits in craters at Mercury’s north pole, and now the MESSENGER spacecraft in orbit around the small planet has visually confirmed it for the first time.

January 27, 1967, Cape Canaveral, Fla.: At 6:31 p.m. Eastern Time at Launch Complex 34 at Cape Canaveral Air Force Station, the frantic word “Hey!” was recorded coming from the cockpit of the Apollo 1 capsule, crewed in a “plugs out” test by astronauts Virgil I. “Gus” Grissom, Edward H. White, II, and space rookie Roger Chaffee. The exclamation was followed by unusual activity recorded inside the capsule by an adjacent camera. A sickening scene would play out for those listening to the transmissions, ending in seconds as the situation grew more desperate inside the capsule as an oxygen-fueled fire ripped through it. It soon transpired that all three astronauts were lost during the accident, culminating in what astronaut chief and colleague Donald K. “Deke” Slayton would call “the worst day” in his book, Deke!, co-authored with Michael Cassutt.

“John, we’re going to fly you one of these days,” Launch Director Bob Sieck called over the communications loop on 15 October 1993. The disappointment of another scrubbed launch attempt was evident in his voice. “Just hang in there.”
“Nice try,” came the call from astronaut John Blaha on Columbia’s flight deck, as he and his six crewmates prepared to disembark from the orbiter after 2.5 hours on their backs in bulky, uncomfortable pressure suits, harnesses, and parachutes. It was the second time that they had been through this routine in trying to get into space for what was to be NASA’s longest shuttle flight to date, lasting a little over two weeks. For mission STS-58—which finally launched on this day (18 October), 21 years ago—would earn its own reputation, not only for its duration, but for the fact that it controversially featured the first euthanasia and dissection of animals in the microgravity environment.

The U.S. Air Force’s mysterious X-37B Orbital Test Vehicle (OTV) ended its third secretive mission today, landing at Vandenberg Air Force Base in Southern California at 9:24 a.m. PDT after spending 674 days in orbit carrying out its secretive mission for the U.S. Air Force Rapid Capabilities Office. Although the Boeing-made X-37B’s existence is public knowledge, its precise mission objectives and ultimate capabilities remain heavily classified.

Many different kinds of exoplanets have been found by astronomers, from giant “hot Jupiters” and “super Earths” to smaller rocky worlds like Earth or Mars. Now, another type has been discovered, an “ice giant” similar to Uranus or Neptune in our own Solar System. The planet is about 25,000 light-years away in the constellation Sagittarius and is one of the first found that appears to be similar to the ice giant planets in our Solar System, Uranus and Neptune, which are part gas and part ice in composition. The discovery was made by an international team of astronomers, led by Radek Poleski, a postdoctoral researcher at Ohio State University.

Site J it is! Philae will touchdown on the comet’s “head” on Nov. 12.
Following a thorough science, engineering, and hazard assessment of the merits of Site J, the European Space Agency (ESA) has given the green light for its Rosetta orbiter to deploy its Philae lander to the primary site on the “head” of Comet 67P/Churyumov–Gerasimenko as the location for the history’s first attempt to touchdown on a comet.
