Epsilon rays are first detected when the baffle plate is torn off an old
"Woden" class freighter during a passage through a comet's radioactive
tail. Primary epsilon rays are created when delta rays bounce off
an ionizing cloud at the edge of a planet's atmosphere (such as an
ozone layer) in such a manner that the elecromagnetic radiation
produced has a helical rather than wave nature. Naturally-occuring
epsilon rays will later be discovered on a satellite orbiting the
star Cepheus in the Arachna region: the crystalline formations
native to this planet having the effect of plane-polarizing primary
epsilon waves with the resulting emission of spiroid (single
spiral) epsilon waves, causing the compression of the DNA helix
[MRM, Te/a].

The first Earth-alien starship crews reflects Terra's increasing
interaction with alien cultures, as demonstrated by the U.N.S.S.
"Pollux's" Human Captain Shu Tse Sum and Vulcan communications
officer, Supak [SFC].

The "Keller" class ambulance vessels are decommissioned [SFC].

2084
The "Ceres" expedition is lost. They are later believed to have founded
the Ten Tribes of Capella IV [STM, ST 3, TWF].

Note that another possibly lost ship, crewed by Alpha Centaurians,
may have colonized Zeta Bootis III (Neural) during this time period
[PLW, TWF].

"Edison" class 58-man interstellar research ships (also known as the
DY-1000 series) begin gathering new information on antimatter in the
interstellar void. Designed as extra-solar probe ships, this class has
inadequate shielding and speed to transit the oort cloud at the edge of
the Sol system and therefore never leaves the solar system [SFC, STD2].

Molly O'Brien, living alone for a decade on Golana, is finally retrieved
by her father in 2374--in one timeline [DSN 548].

2085, August [reference stardate 0/8508]
An unknown disease spreads through Terra's 200-man research base on Pluto,
leaving no survivors. The disease is later linked to a contaminated
souvenir brought in by a careless Orion trader. This is the first
unpleasant incident between Terrans and Orions, and helps to set the tone
for future relations [SFC, FASA, TWF].

The "Assist" class space tower, 20-man, warp driven vessels enter service
[SFC].

2086
A feud starts between the Lornak and Tralesta clans on Acamar III
[TNG 157].

On Omega IV it is the Year of the Red Bird (plus or minus 5 years) [OG].

2087, 31 March
The S.S. "Ark" (UESPA 15), yet another sublight generation ship variant,
is launched from Mars on a heading for Tau Ceti with a crew of 600 [STD2].

The beginnings toward a United Federation of Planets is taken, and
possibly the first call for a United Federation is made. The first Babel
Interplanetary Conference is held and Tatiana Bilash is one of the elder
statepersons present [GN 2, FASA, SFC].

The stardate dating system is established [GN 2, SFC, FASA].

2089
Zefram Cochrane takes his last interstellar voyage [Mt, STM].

In the "Mirror" universe, Zefram Cochrane, plagued by guilt for placing
faster-than-light travel in Joachim's hands, flees into deep space [TBoT
#14].

Earth vessels encounter the Vegan Tyranny. The decisive actions of
the S.S. "Cochrane" and S.S. "Krushchev" cruisers prevent a major
interstellar war [EOM, ST 2].

This is roughly the era of the dawn of a galaxy-wide revolt. In the
unspecified Tholian Galaxy, scientists of the Seltorian subject race
stumble upon a shield cracker wave pattern that will disrupt webs. The
Seltorians quickly develop this into a weapon known as the Web Breaker,
in secret. These units are produced in mass quantities at Seltorian
shipyards, within the next decade, and installed aboard Seltorian war-
ships. The Tholians will discover their activities a decade too late, and
a galaxy-wide Seltorian Revolution will last only a few years [SFB].

2090
The "Monticello" class cargo carriers are decommissioned [SFC].

2092
The U.E.S. "Hernan de Soto" charts the water world Okeanos (Eris V)
while making a side-trip to do a close-range study of a pulsar 25 light
years distant, during the First General Survey. The primary is officially
named Joan-Marie's Star, after the ship's navigator [TOS #66].

Montcalm Daystrom is born on Centauri B II. He will grow up to be
Zefram Cochrane's personal assistant [GN 18].

2093
The "Liberty" class is decommissioned [SFC].

2095
Sarpk becomes famous on Vulcan for his Vulcan lyrettes [TM].

The Earth colony ship makes planetfall on Okeanos (Eris V) [TOS #66].

The "Verne" class cruisers and "Amity" shuttles are decommissioned [SFC].

The "Franklin" class interstellar scouts are decommissioned [SFC].

2096
Rudimentary subspace technology is developed during this era [V 150].

2097
The groundwork for the United Federation of Planets is layed out in
San Francisco on Earth. The Second History alternate timeline begins
when Romulan androids from 2264 A.D. assassinate Dr. Palmer and his
two associates. As a result, the prospace exploration faction loses
much of its status. After several years Earth begins to exhaust its
natural resources and its nations begin fighting among themselves
until the environment is almost totally destroyed [TOS #24].

On Vemla, the first androids are constructed, designed as military
hardware [TNG #20].

On Omega IV it is the Year of the Red Bird (plus or minus 5 years) [OG].

The Nexus temporal energy ribbon again passes through our galaxy [ST VII].

2098
The MD1075 series multi-docks end their service lives as do the WP174
work pods [SFC].

This is roughly the era of a galaxy-wide revolt in an unspecified galaxy.
The revolt is against the Tholians, a high-temperature crystalline race of
dictators who had been overlords of their galaxy for centuries. The
subject races are successful, overthrowing the Tholians and forcing them
out of their home galaxy. Among the subject races who rose up and over-
threw them are the Seltorians, a semi-intelligent (possibly genetically-
engineered) race of beings who served as Tholian auxiliaries and lead the
revolt. After the revolution is complete, the Seltorians simply replace
the Tholians as masters of the galaxy-wide empire. The Seltorian
Suzerainty establishes the Seltorian Tribunal, a war crimes commission
charged with finding and destroying the remaining Tholians who escaped.
They will track down most of the fleeing Tholians to a small satellite
galaxy near their home galaxy and smash them before assembling a counter-
revolutionary strike force. However, several other Tholian groups had
escaped (at least toward) nearby galaxies. Some Tholians migrate towards
our galaxy, bringing along their planet/provincial capital in a small
Dyson sphere (by means unknown). They will arrive here around 2187.
Several other groups also depart the galaxy to come to ours. One of these
is based on the former 312th Battle Fleet, which gathers several other
ships and Tholians during the flight. The ships of this fleet are
referred to as "Neo-Tholians" or "New Tholians" even though they are con-
siderably older than the original Tholians, and will arrive in our galaxy
circa 2288. Seltorian hive ships of incredible size are assembled and
sent on long voyages to many different galaxies (including Andromeda and
our own Milky Way). The Seltorian commander Brzk'Girn's hive ship will
reach our galaxy in 2292 [SFB].
