on the topic of humans being the intergalactic “hold my beer” species: imagine an alien stepping onto a human starship and seeing a space roomba™ with a knife duct taped onto it, just wandering around the ship

it doesn’t have any special intelligence. it’s just a normal space roomba. there are other space roombas on the ship and they don’t have knives. it’s just this one. knife space roomba has full clearance to every room in the ship. occasionally crew members will be talking and then suddenly swear and clutch their ankle. knife space roomba putters off, leaving them to their mild stab wounds.

“what is the point?” asks the alien as another crew member casually steps over the knife-wielding robot. “is it to test your speed and agility?”

“no it doesn’t really go that fast,” replies the captain.

“does it teach you to stay ever-vigilant?”

“I mean I guess so but that’s more of a side effect.”

“does it weed out the weak? does it protect you from invaders? do repeated stabbings let your species heal more quickly in the future?”

“it doesn’t stab very hard, it gets us more than it gets our enemies, and no, but that sounds cool — someone write that down.”

“but then what is its purpose?”

“I don’t know,” the captain says, leaning down to give the space roomba an affectionate pat. “it just seemed cool”

2016 Sets Global Temperature Record

We just experienced the hottest year on record…again.

2016 was hotter than 2015, the previous record. And 2015 hotter than 2014, the previous record year.

These record temperatures are all part of a warming trend that dates back to the late-19th century, largely caused by human emissions of carbon dioxide and other gases into the atmosphere.

A lot of this warming trend has been in the last 35 years. In fact, 16 of the 17 warmest years on record have been since 2001.

To help us gather this data, planes and boats travel out from Antarctic research stations to gather information from the Arctic region, in addition to space-based observatories.

Scientists at our Goddard Institute for Space Studies analyze data from 6,300 weather stations, observations of sea surface temperature and Antarctic research stations, all to determine how the average surface temperature is changing.

Scientists at the National Oceanic and Atmospheric Administration separately analyze the same data to track global temperature.

The two agencies reached the same conclusion about 2016’s record-setting heat.

Variations in local weather mean parts of the globe did not experience a record-setting year. Some places still had snow, cold weather and below-record temperatures, but the overall global average was higher than any previous year.

For instance, according to NOAA the average temperature in the 48 contiguous United States was not quite as high as in 2015, which still holds the record.

A combination of space- and land-based measurements gives us a unique perspective on Earth, the only planet we know of that supports life.

This Week @ NASA--April 14, 2017

Cassini and the Hubble Space Telescope, two of our long-running missions, are providing new details about the ocean-bearing moons of Jupiter and Saturn. Hubble’s monitoring of plume activity on Europa and Cassini’s long-term investigation of Enceladus are laying the groundwork for our Europa Clipper mission, slated for launch in the 2020s. Also, Shane Kimbrough returns home after 171 days aboard the Space Station, celebrating the first Space Shuttle mission and more!

Ocean Worlds

Our two long-running missions, Cassini and the Hubble Space Telescope,  are providing new details about “ocean worlds,” specifically the moons of Jupiter and Saturn. 

The details – discussed during our April 13 science briefing – included the announcement by the Cassini mission team that a key ingredient for life has been found in the ocean on Saturn’s moon Enceladus. 

Meanwhile, in 2016 Hubble spotted a likely plume erupting from Jupiter’s moon Europa at the same location as one in 2014, reenforcing the notion of liquid water erupting from the moon.

These observations are laying the groundwork for our Europa Clipper mission, planned for launch in the 2020s.

Welcome Home, Shane!

Shane Kimbrough and his Russian colleagues returned home safely after spending 173 days in space during his mission to the International Space Station.

Meet the Next Crew to Launch to the Station

Meanwhile, astronaut Peggy Whitson assumed command of the orbital platform and she and her crew await the next occupants of the station, which is slated to launch April 20.

Student Launch Initiative

We’ve announced the preliminary winner of the 2017 Student Launch Initiative that took place near our Marshall Space Fight Center, The final selection will be announced in May. The students showcased advanced aerospace and engineering skills by launching their respective model rockets to an altitude of one mile, deploying an automated parachute and safely landing them for re-use.

Langley’s New Lab

On April 11, a ground-breaking ceremony took place at our Langley Research Center for the new Systems Measurement Laboratory. The 175,000 square-foot facility will be a world class lab for the research and development of new measurement concepts, technologies and systems that will enable the to meet its missions in space explorations, science and aeronautics.

Yuri’s Night

Space fans celebrated Yuri’s Night on April 12 at the Air and Space Museum and around the world. On April 12, 1961, cosmonaut Yuri Gagrin became the first person to orbit the Earth.

Celebrating the First Space Shuttle Launch

On April 12, 1981, John Young and Bob Crippin launched aboard Space Shuttle Columbia on STS-1 a two-day mission, the first of the Shuttle Program’s 30-year history.

human: *is heating up food*

alien: why are you doing that?

human: you see i want the particles in my food to vibrate at just the right frequency
