Congratulations to the MABEL team for a successful series of flights this week, as the Proteus aircraft returned to Mojave, CA.

Operation IceBridge will be able to cover more ground (ice?) in Antarctica this field campaign, thanks to a new base of operations at McMurdo

Feature: Don't be fooled by the old-fashioned name – MABEL is testing state-of-the-art laser technology for ICESat-2

Operation IceBridge mission is flying a grid over Greenland -- some of the same paths ICESat-2 will take

ICESat-2 measures Earth's height - and our new educational exhibit can measure yours!

MABEL gets a view of the top of the world

Glaciers, forests, sea ice, lakes, volcanoes... the MABEL team mapped routes for key views

A new NASA campaign to help understand clouds & Arctic warming, starts Sept. 3

Operation IceBridge began its Antarctic campaign, including flights where ICESat-2's orbits will converge.

How do you move a satellite's optical bench across a cleanroom? Very slowly. Watch a timelapse.

Cleanroom team moved ATLAS instrument to the thermal vacuum, to simulate the harsh space environment.

Congrats to the Orbital ATK team that built ICESat-2's spacecraft bus, which passed its pre-environmental readiness review.

The applications team and early adopters met this week to prepare for the influx of of height measurements from ICESat-2.

2015 Arctic Sea Ice Maximum Annual Extent Is Lowest On Record

The future's so bright... ATLAS needs a sunshade

It's been a busy year! Last May our ATLAS team started integration and testing for the instrument. Now, they're preparing to unite the two main sections of the laser.

A milestone: The Optical Bench was successfully mated to the Box Structure! Check out this time lapse captured inside the clean room by Tyler Evans, Optical Engineer.

Take a front-row seat in the clean room, as the engineering team connects the two main sections of ICESat-2's ATLAS instrument.

Science experiments, sped up! At the World Science Festival in NYC. #wsf15

We have our lasers! The integration team installed the primary and backup lasers onto ATLAS, ICESat-2's instrument that will measure heights. #pewpew

NASA will be giving you an in-depth look at what’s going on with sea level rise around the world - a question the ICESat missions are designed to investigate.

Some of the ICESat-2 team -- including Paige the Penguin -- were in Greenland earlier this month!

The ICESat-2 mission was out in the field earlier this month, flying an airborne instrument over Greenland to study how green lasers interact with different types of snow and ice.

For the first time in its seven years of flights, NASA's Operation IceBridge is conducting overlapping campaigns in Antarctica and the Arctic.

What does record low Arctic sea ice mean for cloud cover & planetary energy balance? Find out with an Earth Science Week series of first-hand stories from NASA

ICESat-2’s spacecraft completed a significant risk-reduction testing program last week, to minimize the chance of technical issues uncovered later.

NASA’s Operation IceBridge, an airborne survey of polar ice, recently finalized two overlapping campaigns at both of Earth’s poles.

2015 saw many highlights at NASA Goddard - including the building and testing of ICESat-2's instrument, ATLAS.

Congratulations to the ATLAS team on their instrument assembly! Engineers fastened on the door - the final component.

Thanks to the ICESat-2/SCAD Collaborative Student Project for the excellent design of our new banner, hanging by the Goddard clean room.

ATLAS passed its Pre- Environmental Readiness Review -- a 2-day review, with 100s of slides presented to the review board.

EMI testing for ICESat-2's instrument, ATLAS, is complete! Next up - Acoustics & Vibration tests

The ATLAS instrument was blasted with noise as NASA Goddard engineers conducted an acoustic test, designed to simulate the roar of a rocket launch

ATLAS moves into the Thermal Vacuum Chamber at NASA Goddard to prepare for testing.

ICESat-2 visits the 'Chill Zone' at National Building Museum's Icebergs exhibit

While NASA Operation IceBridge was in Barrow, Alaska, several of the pilots, scientists and flight crew visited a local summer camp.

Take a look at the 'new normal' of melting sea ice

What's in these crates? Our laser altimeter exhibit!

New EO for Kids magazine features ICESat activity

As IceBridge flies its 2016 Antarctic campaign, scientists also collect spectacular photos

All together now! ICESat-2 is ready for testing, as engineers at Orbital ATK have attached the ATLAS laser instrument to the spacecraft.
