NASA's Juno mission to Jupiter, which has been in orbit around the gas giant since July 4, 2016, will remain in its current 53-day orbit for the remainder of the mission. This will allow Juno to accomplish its science goals, while avoiding the risk of a previously-planned engine firing that would have reduced the spacecraft's orbital period to 14 days. "Juno is healthy, its science instruments are fully operational, and the data and images we've received are nothing short of amazing," said Th...

Tomorrow, a Space-X Dragon cargo ferry will be launched to the International Space Station packed with supplies, experiments, tools and food for the six astronauts living and working high above Earth. In the unpressurised cargo hold is a new NASA sensor that will monitor our atmosphere with a helping hand from ESA. The Space Station flies 400 km above our planet at 28 800 km/h, experiencing 16 sunrises, sunsets, moonrises and moonsets every 24 hours. This orbit is lower than most satellites a...

Going to space is never routine, and Sentinel-2 mission controllers are leaving nothing to chance as they prepare for the critical days following next month's liftoff. Launched in 2015, ESA's Sentinel-2 mission is using the first of two near-identical 'colour-vision' satellites to deliver sophisticated information that is central to Europe's Copernicus programme. Now, the Sentinel-2A craft is about to be joined by its twin, Sentinel-2B, which will complete the pairing that will cover all E...

Today, ground control in Belgium switched off a package that had been continuously watching the Sun from the International Space Station for nine years. 'Solar' has been measuring most of the radiation emitted by our closest star across the electromagnetic spectrum. Built to run for only 18 months, it was still working until today - exceeding all expectations. Solar's observations are improving our understanding of the Sun and allowing scientists to create accurate computer models and pred...

For the first time, scientists using NASA’s Hubble Space Telescope have witnessed a massive object with the makeup of a comet being ripped apart and scattered in the atmosphere of a white dwarf, the burned-out remains of a compact star. The object has a chemical composition similar to Halley’s Comet, but it is 100,000 times more massive and has a much higher amount of water. It is also rich in the elements essential for life, including nitrogen, carbon, oxygen, and sulfur. These...

    Cosmic rays in star-forming galaxies

    Cosmic rays and magnetic fields shape space weather. My primary work in astronomy is understanding the “space climate” of galaxies: how cosmic rays and magnetic fields interact with matter and starlight in the space between stars and regulate star formation. I constrained the properties of cosmic rays in other galaxies and in distant regions of the Milky Way from radio and gamma-ray emission. I concluded that interstellar plasma turbulence controls their magnetic fields.

    Example Papers

    Cherenkov telescopes for visible light remote sensing

    The highest energy gamma-rays are observed using Cherenkov telescopes stationed on the ground. These are giant telescopes (up to 10 meters in aperture) that detect the <1 ms long flash of light emitted when gamma-rays hit the upper atmosphere. They collect enormous amounts of light – comparable to the largest normal telescopes – but have poor angular resolution. I showed that these instruments are excellent for making measurements of bright astronomical sources, and calculated signal-to-noise ratios for photometric, spectroscopic, and polarimetric observations. I also demonstrated how they could be used for remote sensing of objects in the Kuiper Belt, using Fisher matrices and Bayesian models. The use of Cherenkov telescopes as receivers for optical laser communications has been proposed.

    Papers

    “Cherenkov Telescopes as Optical Telescopes for Bright Sources: Today's Specialised Thirty Metre Telescopes?” (2011) by Lacki in The Monthly Notices of the Royal Astronomical Society volume 416, pg. 3075-3082

    “On the Use of Cherenkov Telescopes for Outer Solar System Body Occultations” (2014) by Lacki in The Monthly Notices of the Royal Astronomical Society volume 445, pg. 1858-1877

     

    Generalized interferometry

    Standard interferometry applies the Fourier transform of electric field measurements to reconstruct the direction that radio waves are coming from. I have shown how interferometry could be generalized with other transforms. The entire class of Linear Canonical Transforms allows one to instantiate a linear optical system digitally. Of special importance is the Fractional Fourier Transform, which allows an interferometer to focus on nearby sources rather than at infinity, an important consideration for satellites in low Earth orbit. I also noted that the signal can be decomposed in time with non-Fourier transforms, which could prove useful for brief radio pulses.

    New methods in SETI

    The viability of space travel is directly related to the Search for Extraterrestrial Intelligence (SETI) by Fermi’s Paradox. As an independent researcher, I have explored the feasibility of “cosmic engineering” enabled by interstellar travel. I demonstrated that it is possible to collect starlight very efficiently on planetary, stellar, and galactic scales using smart dust fashioned into resonant dipole antennas. The lack of such engineering strengthens Fermi’s Paradox. Other work includes the feasibility of cosmic-scale particle accelerators, Bayesian estimates for the rate that intelligence evolves on planets, and the commonality of the mysterious “Boyajian’s Star” phenomenon.
