Update 2014/10/28 4:57pm - The Antares rocket exploded right after lifting off the launch pad. Nobody injured, but it destroyed everything on board.
This is a busy week for primary and secondary school space research. The SpaceX Dragon landed in the Pacific Ocean on Saturday returning 28 student experiments from the International Space Station. Tonight an Orbital Sciences Antares rocket launches the Cygnus cargo module - with 18 more student experiments - to the International Space Station. 310,000 students across America and Canada have taken part in space research - with little burden on the ISS astronauts or Nasa’s budget - but some in Congress think that’s a bad thing.
What Could Possibly Be Wrong With That Congress?
American citizens - and their counterparts in nations around the world - saw Nasa spend billions of their own tax dollars to build the International Space Station. Now Nasa repays the favor by letting our aspiring scientists in primary and secondary school use the space station to conduct research of their own. At a time when science education, particularly in the United States, suffers from a lack of investment, how could anybody criticize programs like this?
Senator Tom Coburn can. The Oklahoma Senator issued his annual “Wastebook” that targets examples of what he believes are wasteful or excessive government projects - including the International Space Station. In particular he points at the student research projects:
While encouraging young people to take an interest in science is an important goal, the billions of dollars being borrowed to support space station science fair experiments could make a bigger impact in the lives of these and other children in many more cost effective ways.
Oh really? The Quest Institute and its partner schools bear the full burden of the costs to reach space. In an open letter to Senator Coburn, Student Spaceflight Experiments Program Director Dr. Jeff Goldstein points out that:
Fifty grand - not billions. And once on the station, the experiments themselves require little attention from the astronauts. The Quest Institute’s NanoLab is completely autonomous. The astronauts just have to unload it from the cargo craft and pack it up in the Dragon at the end. Activating the SSEP experiments are a simple matter of bend-shake-and-forget.
You can criticize Nasa for a lot of things, but one thing they aren’t doing is spending “billions of dollars” on “science fair experiments.”
How Does Student Spaceflight Happen?
Most of these projects get into space thanks to the Student Spaceflight Experiment Program. Over the past 4 years, the SSEP helped 91 student experiments reach the International Space Station - giving over 310,000 students in 31 states, the District of Columbia, and 2 Canadian provinces hands-on experience in the way space research is done from proposal through the presentation of results.
SSEP director Jeff Goldstein told the Tampa Bay Observer: “We don’t refer to these students as kids. They are microgravity researchers. They are asked to do everything professional researchers are asked to do. That flight team designed a real experiment, wrote a real proposal, beat out their colleagues, went through a flight safety review and now they are about to launch. It really is a remarkable achievement.”
The SSEP research projects rely on devices called MixStix from space research company NanoRacks. Each MixStix has 1, 2, or 3 chambers that contain the experiment’s materials. When the ISS astronauts bend the MixStix, the seals between the chambers break. A quick shake mixes the materials, allowing the experiment to begin. The astronauts spend almost no time at all.
The California-based Quest Institute for Quality Education uses a larger NanoRacks device for its ISS Partner Organization Program. NanoRacks - the first commercial laboratory in space - took a module CubeSat-based approach to make microgravity research easier for scientists and for astronauts in space. The NanoLab is a CubeSat- shaped module that plugs into the orbital laboratory. All astronauts need to do is plug it in and flip some switches. The experiments run on their own without any further involvement by the ISS crew. The Quest Institute sub-divides their NanoLab so up to 8 schools can fly their own experiments into space.
Student Research Rides a Dragon Home
A SpaceX Dragon module parachuted into the Pacific Ocean on Saturday, bringing Nasa’s month-long Commercial Re-Supply Mission 4 (CRS-4) to a close. Several student experiments were among the nearly 1,500 kilograms of cargo and science samples that the Dragon brought safely to Earth - including the Quest Institute’s NanoLab module and the SSEP’s Mission 5 experiments.
The Quest Institute’s NanoLab modules included 13 experiments from 5 schools and 2 after-school organizations.

- “The Production of Antibiotics from Bacillus subtilis in Microgravity” Montachusett Regional Vocational Technical School, Massachusetts. Astronauts may not always rely on resupply from Earth, so they will need to produce their own drugs. The students will see how well the antibiotic-producing bacteria handles long-term conditions in space.
- “If you cut a Dugesia Planarian worm would it grow back in microgravity?” North Attleboro Middle School, Massachusetts. Biologists use Dugesia Planaria to study basic processes in life sciences and draw parallels to human biology. These students will study the rate of healing in microgravity.
- “Oxidation in Space” St. Peter’s School, Missouri. The students will study whether iron nails rust faster or slower in microgravity compared to Earth.
- “Polyhydroxyalkanoate Production in Zero Gravity” Brookhaven Academy, Mississippi. The bacteria Ralstonia eutropha produces a plastic called polyhydroxyalkanoate (PHA) that’s used in medical implants. Since future scientists might grow or 3D-print their own medical supplies, the students want to see how well the bacteria handle microgravity.
- “Penicillium Growth Rate in Microgravity” Pennsauken Phifer Middle School, New Jersey Drug companies used to farm the antibiotic penicillin by extracting it from the penicillium mold. The students want to see if future astronauts could make their own antibiotics by using these natural drug factories.
- “What is the effect of microgravity on mold growth on white bread?” New Explorations into Science, Technology, and Mathematics, New York. A piece of white bread may grow mold during the months that the experiment spends in space. The students will compare the rate of mold growth to control experiments on Earth.
- “Lettuce Growth” Cottage Lane Elementary School, New York. Like their Florida counterparts, these students want to see how well lettuce handles conditions in the space station.
- “Artificial Ear?” Mendenhall Middle School, North Carolina. Jellyfish sense direction using small hairs connected to crystals within their bodies. In space, though, jellyfish lose all sense of direction. The students want to see whether that’s caused by a different rate of crystal growth in microgravity.

The Yankee Clipper mission also includes a university experiment sponsored by the District of Columbia Space Grant Consortium to encourage women and minorities to pursue science and math related careers. In the project “The Effects of Microgravity on the Development of Chrysanthemum morifolium Seeds” undergraduates at George Washington University and Georgetown University will study how well chrysnthemums - potential air recycling plants - develop in space.
Senator Coburn wants to know how Nasa could let this happen? The question should be: Why doesn't Nasa do more?
