NASA news: Danger asteroids can wipe out ENTIRE cities leaving millions dead | Daily Star

Smaller asteroids can also be devastating, like the 60-foot-wide Chelyabinsk meteor that went undetected until it exploded over Russia and injured a thousand people.A space rock bigger than that over a more populated area would have caused more damage.

Near the Stony Tunguska River, Russia, back in 1908, a huge asteroid smashed into the a forest.

The rock, estimated as being between 200 to 620ft, left an enormous crater and knocked down 80 million trees.

Apollo Moon Landing Mystery Solved By Discovery Of Long Lost NASA Tapes

The big Moon mystery has now been solved. And yes, humans are to blame.

A decades-old lunar mystery has now been solved thanks to the recovery of once lost data tapes and a massive amount of sleuthing.

The results confirm that inexplicable changes in the moon’s temperatures recorded in the 1970s were not the result of some strange inner heat source, but rather the by-product on astronauts stomping around and stirring up moon dust.

(san jose mercury news) – Pluto pictures pouring in; scientists riveted by ‘over the top’ images

CAPE CANAVERAL, Fla. (AP) — The spigot has opened again, and Pluto pictures are pouring in once more from NASA’s New Horizons spacecraft.

These newest snapshots reveal an even more diverse landscape than scientists imagined before New Horizons swept past Pluto in July, becoming the first spacecraft to ever visit the distant dwarf planet.

“If an artist had painted this Pluto before our flyby, I probably would have called it over the top — but that’s what is actually there,” said Alan Stern, New Horizons’ principal scientist from Southwest Research Institute in Boulder, Colorado.

In one picture, dark ancient craters border much younger icy plains. Dark ridges also are visible that some scientists speculate might be dunes.

One outer solar-system geologist, William McKinnon of Washington University in St. Louis, said if the ridges are, in fact, dunes, that would be “completely wild” given Pluto’s thin atmosphere.

“Either Pluto had a thicker atmosphere in the past, or some process we haven’t figured out is at work. It’s a head-scratcher,” McKinnon said in a written statement.

The jumble of mountains, on the other hand, may be huge blocks of ice floating in a softer, vast deposit of frozen nitrogen.

After several weeks of collecting engineering data from New Horizons, scientists started getting fresh Pluto pictures last weekend. The latest images were released Thursday.

Besides geologic features, the images show that the atmospheric haze surrounding Pluto has multiple layers. What’s more, the haze crates a twilight effect that enables New Horizons to study places on the night side that scientists never expected to see.

Monday marks two months from New Horizons’ close encounter with Pluto on July 14, following a journey from Cape Canaveral, Florida, spanning 3 billion miles and 9½ years. As of Friday, the spacecraft was 44 million miles past Pluto.

So much data were collected during the Pluto flyby that it will take until next fall to retrieve it all here on Earth. The spacecraft is operated from the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, which also designed and built it.

New Horizons’ next target, pending formal approval by NASA, will be a much smaller object that orbits 1 billion miles beyond Pluto. It, too, lies in the so-called Kuiper Belt, a frigid twilight zone on the outskirts of our solar system. Following a set of maneuvers, New Horizons would reach PT1 — short for Potential Target 1 — in 2019.

(pioneer news) – Scientists Report Discovery of Oldest Galaxy Yet Known

Just this week, a team of researchers out of the California Institute of Technology (Caltech) has reported the discovery of a new galaxy—which they call EGS8p7—estimated to be in the distant space “neighborhood,” and has been estimated to be about 13.2 billion years old. Scientists say, then, that this universe must be about the same age as the universe—born about 600,000 years later than the Big Bang.

“We report the discovery of Lyman-alpha emission (Lyα) in the bright galaxy EGSY-2008532660 (hereafter EGSY8p7) using the Multi-Object Spectrometer For Infra-Red Exploration spectrograph at the Keck Observatory,” explains the study researchers. Furthermore, the research paper adds, “Redshift results from the Doppler effect, the same phenomenon that causes the siren on a fire truck to drop in pitch as the truck passes.”

In addition, NASA Hubble astronomy post-doctoral scholar Adi Zitrin comments, “If you look at the galaxies in the early universe, there is a lot of neutral hydrogen that is not transparent to this emission. We expect that most of the radiation from this galaxy would be absorbed by the hydrogen in the intervening space. Yet still we see Lyman-alpha from this galaxy.”

Of course, this is just a new discovery so much more research is necessary before reaching any conclusions. At the same time, scientists know that data from this galaxy will certainly provide us with new insights into the evolution of our solar system.

Zitrin concludes, “We are currently calculating more thoroughly the exact chances of finding this galaxy and seeing this emission from it, and to understand whether we need to revise the timeline of the reionization, which is one of the major key questions to answer in our understanding of the evolution of the universe.”

NASA astronaut Kjell Lindgren, Oleg Kononenko of the Russian Federal Space Agency (Roscosmos) and Kimiya Yui of the Japan Aerospace Exploration Agency (JAXA) joined their Expedition 44 crewmates when the hatches between the Soyuz TMA-17M spacecraft and the International Space Station officially opened at 12:56 a.m. EDT.

Expedition 44 Commander Gennady Padalka of Roscosmos, as well as Flight Engineers Scott Kelly of NASA and Mikhail Kornienko of Roscosmos welcomed the new crew members aboard their orbital home.

The crew will support several hundred experiments in biology, biotechnology, physical science and Earth science — research that impacts life on Earth.

Kjell Lindgren and Kimiya Yiu are now the 217th and 218th people to board the International Space Station. This is the first visit for both Lindgren and Yiu, and the third for Kononenko.

Lindgren, Kononenko and Yui will remain aboard the station until late December. Kelly and Kornienko, who have been aboard since March 27, will return to Earth in March 2016 at the end of their one-year mission. Padalka, who also has been aboard since March 27, will return to Earth in September, leaving Kelly in command of Expedition 45. Kelly and Kornienko will return to Earth in March 2016 with Expedition 46 after 342 days in space.

You can follow the crew’s activities in space on social media. Follow space station activities via Twitter, Facebook, and Instagram. Follow Twitter updates from Kjell Lindgren, Kimiya Yui, and Scott Kelly, and follow Kelly on Instagram.

On-Orbit Status Report

43 Soyuz (43S) Launch/Dock: 43S launched at 4:02 PM CDT today and docked at 9:46 PM CDT. Hatch opening occurred at 11:56 PM CDT. With the arrival of Kjell Lindgren, Kimiya Yui and Oleg Kononenko the ISS returns to 6-crew operations. Following crew ingress, the ISS Safety Briefing will be performed to familiarizes the newly arrived crew with potential hazards and safety measures. The crew will also review emergency actions, roles and responsibilities and response to depressurization, fire and toxic events.

Fine Motor Skills: Kelly and Kornienko performed their Flight Day 120 session of Fine Motor Skills today. In this experiment crew members perform a series of interactive tasks on a touchscreen tablet. The investigation is the first fine motor skills study to measure long-term microgravity exposure, different phases of microgravity adaptation, and sensorimotor recovery after returning to Earth’s gravity. The goal of the experiment is to answer how fine motor performance in microgravity trend/vary over the duration of a six-month and year-long space mission; how fine motor performance on orbit compare with that of a closely matched participant on Earth; and how performance trend/vary before and after gravitational transitions, including the periods of early flight adaptation and very early/near immediate post-flight periods.

Space Headaches: Yui and Lindgren will perform their first Space Headaches questionnaire following their arrival on ISS. They will complete the questionnaire daily for their first week on orbit then once per week for the remainder of their mission. Headaches can be a common complaint during spaceflight. The Space Headaches experiment improves the understanding of such conditions which helps in the development of methods to alleviate associated symptoms and improve the well-being and performance of crew members in orbit. This can also improve the knowledge of similar conditions on Earth.

Russian Segment (RS) Extravehicular Activity (EVA) Preparations: Kelly gathered and transferred US tools in preparation for RS EVA #41 currently planned for August 10. Battery maintenance for Rechargeable EVA Battery Assemblies (REBA), Helmet Lights (HL), and Pistol Grip Tools (PGT) started last week will conclude this Friday.
