NASA Social at Dryden – NASA’s Airborne Science Program

On January 25, 2013 some 50 spacetweeps gathered at NASA Dryden in California's Mojave Desert, looking forward to a day of Science Adventures as guests invited with social media accreditation. The hash tag for the event is #NASA_Airborne and this is the badge:

We were about to learn a lot about NASA’s Airborne Science Program comprising almost 30 suborbital Earth Science instruments and 10 active missions campaigns. Many of the aircraft are stationed at Dryden and as such provide a fully functional and staffed “motor pool” for the science community.

NASA's Airborne Science Aircraft

Highlights from the day’s program:

Global Hawk

The Global Hawk is an autonomous, high-altitude science aircraft. It has 32 hours of endurance, a range of 11,000 miles and a maximum altitude of 65,000 feet. The plane can carry large payloads while monitoring and measuring remote locations on Earth that are not easily accessible by satellite and by piloted or remotely operated aircraft.  (So, yes, you could argue that it’s pretty much a sophisticated robotic spy plane that *will* find you on the Earth’s surface if it’s really looking for you.) At NASA Dryden, however, the Global Hawk is used for airborne science missions. The 44-foot-long aircraft is powered by a single Rolls Royce engine and has an impressive wingspan of 116 feet.

Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR)

This reconfigurable radar system provides important data for studying earthquakes, surface movements and other dynamically changing Earth events, such as oil spills, landslides and glacier movements. The instrument is designed to be operated on an uninhabited aerial vehicle (UAV) but is currently being demonstrated on a piloted NASA C-20A aircraft. UAVSAR operates at 40,000 feet and will be conducting earthquake fault monitoring flights over Baja California in upcoming weeks.

Surface, Water, Ocean, Topography (AirSWOT)

AirSWOT is an airborne instrument suite that will make the first-ever global survey of Earth’s surface water, including phenomenology, ocean and hydrology studies. The collected data can be used to produce topographic maps of water surfaces and flood plains at centimeter-level accuracy. AirSWOT will be hosted in a King Air B200 aircraft platform.

Stratospheric Instrument for Infrared Astronomy (SOFIA)

SOFIA is the largest airborne observatory in the world.  It studies the universe at infrared wavelengths, capable of making observations that are impossible for even the largest and highest ground-based telescopes. The SOFIA observatory is mounted inside a modified Boeing 747. I have always wanted to see SOFIA and I was not disappointed. SOFIA looked majestic, even in the hangar, gleaming, looking brand-new in the muted light, proudly displaying NASA’s collaboration with the German Aerospace Center (DLR). 

Another famous modified 747 is also at Dryden – One of the two space shuttle carrier aircraft (SCA) used to ferry NASA’s orbiters around the country.  The SCA had been in service for a long time, required major overhauls and has been permanently retired to Dryden as a source of spare parts for SOFIA.

Thank you, NASA Dryden staff for a wonderful day immersed in Science!

So what do you really do at a NASA Social?

Welcome to Los Angeles, Endeavour!

Space Shuttle Endeavour arrived safely and to a huge welcome at Los Angeles International Airport on Friday, September 21, 2012.

Since it's easy to get caught up in the excitement of seeing a space shuttle soar overhead on top of a modified 747 (aka SCA = shuttle carrier aircraft) let's take a look at a rare photograph first. Below is Endeavour in her full splendor docked to the completed International Space Station during her last mission to space. Italian Astronaut Paulo Nespoli snapped this picture on May 23, 2011 from a Soyuz capsule. While there are a number of photos showing parts of shuttles photographed from inside the ISS, this is the only picture showing all of Endeavour docked to the completed ISS. This picture shows her doing what she was made for: Spaceflight. Building and servicing the International Space Station. An amazing machine that gave us the ability to construct a human outpost in orbit. Endeavour may be ready for retirement now and I can't wait to visit her at her new home at the California Science Center. I'm sure she will be breathtaking. 

But to me she was never more magnificent than doing what she did best - In Space.

Around 9 a.m. on Sept. 21, I started making my way to LAX a few miles away. I took the bus and train to avoid the predicted traffic chaos and shortage of parking at the location I had in mind: The East Side of Aviation Blvd, at the end of LAX's south runway. If you know the area, this stretch of road is located north of the Proud Bird restaurant. The runway starts on the other side of the street. It's a great spot for watching incoming planes fly low before touchdown. 

I arrived at the location at 10:30 a.m, as planned, for a shuttle landing time of 11 a.m., just as I learned that landing time had been postponed to 12:45 p.m. Aviation Blvd. is not one of those quaint, picturesque L.A. streets. It's a major four-lane airport access road and the ambiance is razor wire fence-industrial. The "sidewalk" is a narrow strip of gravel.  (Note: If you ever find yourself stranded on a narrow strip of gravel for a long wait, do so with a Southwest flight attendant who has a carry-on. They have everything you need in that bag for hot, dusty, historic space events!)

When I arrived, the crowd was still relatively thin. I settled in for a 2+ hour wait. Twitter dropped in and out of being accessible during that time so my #spottheshuttle tweets from the location are a bit... spotty. 

As I have found to be the case at all space events, nothing is easier than striking up a conversation with strangers. I met two flight attendants from Southwest Air, one who had come from Minneapolis, the other Las Vegas. I met an engineer who had worked on Endeavour's SSMEs. A mother who had brought her kid to see the shuttle; they had been waiting since 6 a.m. Two film students with professional equipment who planned to get footage of the landing and use it in their film project this semester, and many more. As a bonus, I got a ferocious sunburn despite SPF50. No matter.

By noon, the crowd had grown considerably and was now clustered along Aviation Blvd. in both directions as far as anyone could see. The cops amused us trying to contain everybody on the gravel strip, keeping them out of the bike path and street. This was a doomed effort. The bike path was ours. During the shuttle's final landing approach, the cops caved in, stopped traffic and let us take the street. That is when the long, dusty, brutally hot wait paid off. This is what we saw - no zoom, no filters, a glorious moment:

The aircraft in the upper right is an F-19 fighter aircraft, one of two that accompany the shuttle carrier aircraft (SCA), a converted 747, flying space shuttles across the country. While the shuttle program was active, NASA maintained two SCAs to return shuttles from California. Shuttle landings were diverted to land at Edwards Air Force Base in California on a number of occasions.

The landing approach was Endeavour's third pass above us. We first glimpsed the plane carrying Endeavour as a speck in the northwest, from the direction of Santa Barbara, heading inland over Santa Monica, beginning its flyby of L.A. landmarks, including Griffith Observatory and Jet Propulsion Laboratory. The SCA then headed south, where it flew over Disneyland, Boeing and the U.S.S. Iowa. It then returned to LAX and gave us two approaches: The first one much higher than the above pic; even though it looked like it might land. At the last moment, the 747 pulled up and completed one last long loop to the southeast toward its final landing approach.    Welcome to Los Angeles, Endeavour! We are proud to have you. I will see you again during the parade to the CA Science Center on October 12. Below is a collection of some of my favorite photos.

 You don't see this every day: Angelenos stop and get out of their cars along a busy airport access road to get a better look at History in the Making. 

By Saturday afternoon, Endeavour had been de-mated from the SCA. This marks the first time Endevour was seen nose-to-nose with a NASA shuttle carrier aircraft
