Frontier of Science

A list of subjects at the frontier of scientific discovery has been compiled in Table 16-01. It will be updated whenever new information is available.

Subject Objective Projects Measurement Status
Cosmological Model To determine parameters in the model Wilkinson Microwave Anistropy Probe (WMAP) Age and geometry of the Universe, evidence for inflation First detailed map released on February, 2003; mission has been extended beyond 2008
Dark Energy To identify the nature of dark energy Wilkinson Microwave Anistropy Probe (WMAP) Result seems to favour cosmological constant over negative pressure (quintessence) On-going
Dark Energy To confirm acceleration of the cosmic expansion SuperNova Acceleration Probe (SNAP) Discovery of many type Ia supernovae at redshifts greater than any yet found Proposed
Dark Matter To look for unseen massive objects MAssive Compact Halo Objects Project (MACHO) Brown dwarfs or planets in the halo of the Milky Way On-going since 1992
Dark Matter To look for weakly interacting massive particles (WIMP) DAMA and other groups Heavy supersymmetry partners Inconclusive claim in 2000, second claim in 2008 with upgraded detector
Early Universe To observe the first stars and galaxies in the Universe James Webb (formerly Next Generation) Space Telescope (JWST) Highly redshifted and faint infrared objects 2011 (delayed to 2013)
Extra-terrestrial Intelligence To look for extra-terrestrial intelligence Search for Extra-Terrestrial Intelligence Project (SETI) Radio signal of extraterrestrial origin On-going since 1960
Extra-terrestrial Life To look for life in another world ESA, ORIGINS Habitable planets 2014, 2015
Human Genetic Map To compile the Human Book of Life Human Genome Project (HGP) and Celera Human genome Working draft completed on Feb. 2001; 99.99% completed by April, 2003
Quantum Computing To conduct research into all aspects of quantum information processing Centre for Quantum Information and Foundations (CQIF) A quantum computer On-going
Higgs Boson To confirm spontaneous symmetry breaking in gauge theories Experiments at CERN and Fermilab Debris identified to be from the decay of Higgs bosons Inconclusive, LHC will provide more definite answer in 2008
CP-Violation To explain the dominance of matter over anti-matter Experiments at BaBar/SLAC and Belle Quantum interference between two decay modes of the B0 meson Observed, but the result is not consistent with the matter anti-matter ratio
Neutrino Mass To verify if neutrino has mass Experiments at Super-Kamiokande, SNO, and other facilities Neutrino oscillation between the three generations Observed, but more measurements are needed to select competing theories
Proton Decay To validate GUT (baryon, lepton conversion) Underground detectors at Argonne and other sites Spontaneous reactions which might indicate proton decay No unambiguous event
Superstrings Theory To unify the four interactions and beyond Academic Institutions Testable predictions Not yet available

Table 16-02 Space-crafts on Scientific Missions

Solar System Missions Figure 01 portrays all the space missions past and future with the inner Solar System depicted on the upper right and the outer Solar System on the lower left pictorially. A short description of the future missions is listed below the image. Its first item is the date, follows by the name of the spacecraft, then the acronym of the mission with the planetary object at the end (the weird sounding name of "Churyumov-Gerasimenko" is a comet). The date is not listed after 2018. The acronyms are explained in the lower left corner.
