Paul is currently a graduate student in Space and Planetary Sciences at the University of Akransas in Fayetteville. He grew up in the Kansas City area and developed an interest in space at a young age at the start of the twin Mars Exploration Rover missions in 2003. He began his studies in aerospace engineering before switching over to geology at Wichita State University where he earned a Bachelor of Science in 2013. After working as an environmental geologist for a civil engineering firm, he began his graduate studies in 2016 and is actively working towards a PhD that will focus on the surficial processes of Mars. He also participated in a 2-week simluation at The Mars Society's Mars Desert Research Station in 2014 and remains involved in analogue mission studies today. Paul has been interested in science outreach and communication over the years which in the past included maintaining a personal blog on space exploration from high school through his undergraduate career and in recent years he has given talks at schools and other organizations over the topics of geology and space. He is excited to bring his experience as a geologist and scientist to the Spaceflight Insider team writing primarily on space science topics.

  • Study suggests increased cancer risk on Mars missions

    June 13th, 2017

    A new study by researchers at the University of Nevada, Las Vegas (UNLV) suggests the cancer risk for astronauts on a mission to Mars could be higher than expected. The results of the study were published in the May issue of Scientific Reports and show the risk is effectively doubled compared with previous models.

  • Aerojet Rocketdyne ‘kill vehicle’ performs successful test

    June 6th, 2017

    Last week, Aerojet Rocketdyne announced the 10th successful test of its Divert and Attitude Control System (DACS) on its Exoatmospheric Kill Vehicle (EKV) in the first live-fire missile defense test against an ICBM-class target.

  • Parker Solar Probe details revealed

    June 1st, 2017

    NASA announced on May 31, 2017, a groundbreaking new mission to explore the Sun at close range. The Parker Solar Probe will launch in 2018 and will spend nearly seven years spiraling in toward the Sun, utilizing Venus for seven gravitational assists before making its closest approach of about 3.7 million miles (6 million kilometers) from the Sun's surface.

  • Cassini prepares for sixth ring-grazing orbit

    May 25th, 2017

    NASA's Cassini spacecraft is currently completing its fifth ring-grazing orbit of Saturn as it conducts its Grand Finale nearing the end of its mission. It will reach its orbital apoapsis on May 25 at 08:50 UTC (4:50 a.m. EDT), at which point its sixth ring-grazing orbit will begin. The sixth ring crossing of the Grand Finale will occur on May 28 at 14:22 UTC (10:22 a.m. EDT).

  • Van Allen Probes detect barrier around Earth

    May 20th, 2017

    New results from NASA's Van Allen Probes have revealed the impact humans have on the environment is not limited to physical and chemical effects on the Earth's surface, but it also includes radio frequencies extending out into space.

  • NASA detectors delivered for ESA’s Euclid spacecraft

    May 13th, 2017

    NASA delivered three detector systems for the European Space Agency's (ESA) ground-breaking Euclid mission to study dark matter and dark energy.

  • India announces opportunity for instruments on Venus mission

    May 9th, 2017

    The Indian Space Research Organization (ISRO) is seeking experiments to include on a potential mission to explore Venus. A launch date was not provided for the mission, but it seeks to build on past missions launched by other nations that have included satellites, landers, and atmospheric probes.

  • MUOS-5 Now Supporting Troops with UHF Communications

    April 28th, 2017

    The fifth Mobile User Objective System (MUOS-5) satellite is now delivering secure communications to troops using its Ultra High Frequency (UHF) telecommunications system. This comes as the U.S. Navy, partnered with the Army Forces Strategic Command, have worked to bring MUOS-5 into operation after it successfully completed on-orbit testing on January 19, 2017.

  • Cassini prepares for ‘grand finale’

    April 8th, 2017

    On Wednesday, April 26, 2017, NASA's Cassini spacecraft will conduct the first in a series of 22 dives between Saturn's atmosphere and the gas giant's rings as a part of the mission's “grand finale”. It will conclude a mission that has spent almost 13 years exploring the Saturnian system.

  • Laser communications to provide faster connections for Orion

    April 4th, 2017

    NASA engineers are continuing to push the limits of laser communication technology by developing a new system called LEMNOS that is to be tested on the second flight of the Orion spacecraft just beyond the Moon. Also referred to as optical communication, laser communication between a spacecraft and the Earth holds the promise of allowing higher data transmission rates than are currently possible.

  • Wheel treads break on Curiosity rover

    March 23rd, 2017
